Bay Area Rapid Transit (BART) announced last week that a shutdown, causing an interruption of train service in the San Francisco Bay area, originated from issues with a computer server, according to a KTVU.com report. The report indicates that problems developed during a scheduled upgrade to a network server leading to the disruption.
BART stated on the morning of Friday, November 22nd, which outlined the server upgrade, which was to be executed 12 hours earlier on Thursday, according to the report. The upgrade ultimately began to impact the functionality of the servers and how they exchange information and the overall performance of the computer system, the Operations Control Center, and how it monitors train service.
The report indicates that the central computer went offline on Thursday evening, causing the last scheduled trains to experience delays of approximately two hours. According to the report, train operators and maintenance personnel were forced to move and lock switches to respond to the interruption manually. After long hours of work, BART determined that the scheduled server upgrade caused the issue. The server's configuration was returned to a point previous to the upgrade time, and the problem stopped.
